Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the pattern repeats uniformly throughout the circumference of the tread;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a right side elevational view thereof; the opposite side being a mirror image therof; and,

FIG. 4 is an enlarged fragmentary front elevational view thereof.

In the drawings, the broken line defining the sidewall, inner bead and the peripheral boundary between the tire tread and the sidewall are for illustrative purposes only and form no part of the claimed design.

In the drawings, the dark stippled surface shading represents the recessed portion of the tread grooves, having the depth shown at the top and bottom of FIG. 2.
